Specification of Letters Patent.

Patented Nov. 13, 1906.

Application filed September 1. 1905. Serial No. 276,666.

To all wh/om it may concern;

Be it known that I, WIN I). WILLIAMS, a citizen of the United States,residinflr at Phila delphia, in the County 0f Philadephia and AState ofPenns lvania, have invented certain new and useu Improvements in RotaryOscillatory Reciprocating Engines, of which the following is aspecification.

In the generation andutilization of artifi cial forces many have beenthe attempts to obtain a maximum amount of units of available force fromthe energy developed by the combustion of fuel. It is known that in theo eration of reciprocating engines only a portion of the force of thefluid medium is utilized/i. e., that which acts on the piston to driveit-the remainder acting on the cylinder-head, which is inert andimmovable. This difiiculty has been met by utilizing two pistons andadmitting the motive medium etween them and harnessing the forcerepresented by each. No real advantage results from this constructionbecause the sum of the strokes of each piston may be represented b thesingle stroke of a piston of like area. o this end the engine inoperation is the resultant of a reciprocating, an oscillatory, and arotar movement, all combining in the economica conservation of energy.

The mechanical embodiment of the invention consists of a frame, arelatively rotatable head, an oscillatory engine, a crank-wheel betweenthe engine and rotary head and geared to the frame so as to e'ectrotation of the said rotary head and an oscillation of the en ine, and'a valve mechanism for admitting an exhausting the motive medium fromthe en Ine.

or a full description of the invention and the merits vthereo and alsoto acquire va knowledge of .the details of construction of the means foreffecting the result reference is to be had to the following descriptionand ac- -com anying drawings.

'le the invention may be adapted to different forms and conditions bychanges in the structure and minor details without clepartin from thespirit or essential features thereo still the preferred embodiment isshown in the accompanying drawings, in which- Figure 1 is a verticaltransverse section of an engine embodying the invention about on theline :u :v of Fig. 2. Fig. 2 is a vertical longitudinal section of theengine on the line y y of Fig. 1. 3 is a side view of the engme having aportion broken away to show Inore clearly the relation of the steampassa es and ports. Fig. 4 is a View similar to Fig. 3 of the oppositeside of the engine. Fig. 5 is a section of the engine on the line z z ofFig. 2. Fig. 6 is a detail view of the engine and crankwheel, showingthe disposition of the orts when the piston is at one-half of its stro ein one direction. Fig. 7 is a view similar to Fig. 6, showing therelation of the parts when the piston is at one-half of its stroke inthe opposite direction. Fig. 8 is a detail view of a portion of thecylinder and a plate, showing the cooperating ports.

Corresponding and vlike parts are referred to in the followingdescription and indicated in all the views o? the drawings by the samereference characters.

The main frame of the engine comprises a base 1, heads 2, and a rim orshell 3, the latter preferably having a close it with the heads andprovided upon its inner circumference, which lis circular, withcog-teeth 4. The superstructure of the frame constitutes a casing inwhich the rotary head, engine, and adjunctive parts are located andhoused. The heads 2 are reinforced u on their exterior by means of ribs5, whic have a radial arrangement, and said heads have bosses'at theircenter to provide bearings in which the shaft of' the engine is mounted.

The engine and cooperating crank-wheel are mounted upon a rotary headwhich is located within the casing or u per part of the main frame. I heengine is o the oscillatory reciprocating type and comprises a cylinder6 and piston 7, the piston-rod operating in a stufiing-box 8, closin theopen end of the cylinder and having goose connection with thecrank-wheel 9 by means of a wrist-pin 10 in the manner well understood.The pivotal end of the cylinder 6 is thickened and formed with atransverse o enin in'which is fitted the pivot 11, upon wh mounted foroscillatory movement, said pivot beimT stationary and made hollow andsubdivided by a longitudinal partition 12 to form passages 13 and 14.Openings 15 and 16 are formed at diametrically opposite points of thepivot 11 upon one side of the partition 12, and an opening 17 is formedin a side of the pivot adjacent' to the partition 12 and opening 16. Theseveral openings 15,

ich t e engine is' ICO 16, and 17 constitute steam-ports. An open- Linfy 18 is provided in the outer end of the cyl; inder, and acorresponding opening 19 1s lo- :ated at the inner end, both openings 18and 19 being at diametrically opposite points and leading from thetransverse opening in which the pivot 1 1 is fitted. At the op osite endoi' the cylinder a triangular-shaped3 space 20 is formed in a side wall,and ports 21 and 22 lead therefrom through opposite sides of said wall,said ports 21 and 22 having a right-angular disposition, the outer port21 being lengthwise of the cylinder and the inner port 22 transversethereof and in communication with the wider end of the space 20. Theport 21 is adapted to 'alternately register with ports 23 and 24, formedin a wall of the rotary head, so as to admit steam into the inner end ofthe cylinder and exhaust it therefrom. A live-steam passage 25 is formedin a wall of the rotary head and establishes communication between anend o the pivot 11 and the live-steam ports, and a corresponding passage26 is in communication with the exhaust-ports to carr off the spentsteam. As the engine oscil ates the port 21 thereof' alternatelyconnects with the ive and exhaust ports in the well-known manner toadmit ot supplying steam to the cylinder to drive the piston toward thepivotal end .of the engine and to exhaust the spent steam as the pistonis driven inward or away from the pivotal end of the engine.

The rotary head, which carries the engine and crank-wheel, may be of anyconstruction and preferably comprises companion plates 27, which areconnected by transverse tiebolts 28, the ends of which are reduced andthreaded to pass through corresponding openingsof the plate. The pivot11 is constructed similar to a tie-bolt 28 and performs the sameoiiice--that is, to connect the plates 27. A passage 29 is formed in oneof the plates 27 and is in communication at one end with the passage 14of the pivot 11 and at its opposite end with the opening 30, formedlongitudinally in an end portion of the shaft 31 of the engine, andwhich is in communication with a pipe 32 for supplying steam or otherfluid motive medium for driving the engine. The engine is mountedbetween the plates 27, and the outer end of the piston-rod is connectedwith a transverse rod which corresponds to the wrist-pin 10 and whichconnects a pair of crank-wheels 9, each being mounted upon journals 33,extended inward from the plates 27. The crank-wheels 9 are toothedaround their periphery and mesh with the cog-teeth 4 upon the innercircumference of the rim 3. In the operation of the engine as the pistonis driven inward or away from the pivotal end of the engine and byreason of its toothed connection with the stationary frame bers of thehead carrying said crank-wheel and engine is caused to turn.

Having thus described the invention, what is claimed as new is 1. Incombination, a stationary frame, a rotary head comprising spacedmembers, an oscillatory engine mounted between the members of said head,a hollow pivot supporting said engine and subdivided into longitudinalassages which communicate at opposite en s with passages formed in thememthe rotary head, and a crank-wheel mounted upon said rotary head andoperatively connected with the piston-rod and geared to the stationaryframe to effect rotation of the head in the operation of the engine.

2. In combination, a stationary frame, a rotary head comprising spacedmembers each provided with a steam-passage, a hollow pivot connectingsaid members and having communication at its ends with the passages inthe members of said rotary head, said pivot being subdividedlongitudinally to provide live and exhaust passages, an oscillatingengine mounted upon said valve, a crank-wheel connected with thepiston-rod and co erating gearing crank-wheel and enginerame.

3. In combination, a frame comprising a casing, a rotary head housedwithin said casing and comprising spaced members, each provided with aradially-disposed passage, a hollow pivot having communication atopposite ends with the passages of said members, an oscillating enginemounted upon said hollow pivot, companion crank-wheels journaled to therotary head and operatively connected with the piston-rod, andcooperative gearing between the crank-wheels and rim of said casing.

4. An engine comprising a cylinder and a piston arranged to reciprocatetherein, a rotary support having the engine cylinder mounted thereon foroscillatory movement, a toothed crank-wheel mounted upon said rotarysupport and having the piston-rod connected thereto, and a toothed rimhaving the toothed crank-wheel coperating therewith and having itscenter coinciding with the axis of the aforesaid rotary support, theaxes of the engine-cylinder and crank-wheel being upon opposite sides ofthe axis of the rotary support and in the same straight line therewith.

In testimony whereof I affix my signature in presence of two witnesses.
